This study examined if subcortical stroke was associated with impaired facial emotion recognition. Furthermore, the lateralization of the impairment and the differential profiles of facial emotion recognition deficits with localized thalamic or basal ganglia damage were also studied. Thirty-eight patients with subcortical strokes and 19 matched nor...

Previous data have suggested that ecstasy use may affect cognitive functions. The relationship between ecstasy use and emotion recognition remains largely unknown. This study reports the findings on the neuropsychological effects of ecstasy use on recognition of basic human emotions among 100 abstinent ecstasy users, along with 100 demographically...

Previous studies on the effects of ecstasy on neuropsychological performance have often recruited small sample sizes. The present study was conducted to validate previous findings regarding the effects of ecstasy consumption on neuropsychological performance. A comprehensive neuropsychological investigation was conducted in 100 abstinent ecstasy us...

This study investigated the role of sub-cortical brain structures in emotion recognition. Fourteen patients (eight left, six right) with sub-cortical brain damage (SS) and 14 matched healthy volunteers (HV) were recruited. A brief neuropsychological battery was administered to measure working memory, visual inattention, Stroop effect and visual org...

The purpose of the present study is to investigate whether patients with different subtypes of schizophrenia are differentially impaired on measures of attention. Forty-eight patients with schizophrenia (19 paranoid and 29 nonparanoid) and 48 healthy controls (matched on chronological age, sex, and years of education) were administered five measure...

Emotion recognition (ER) was examined in 64 patients with idiopathic Parkinson's disease (PD; 56 bilateral and 8 right-sided) and 64 matched healthy volunteers. Participants were administered an ER battery, consisting of the following subscores: overall ER (OER), overall facial ER, facial emotion identification (FEI) and discrimination, overall pro...

The frontal fluency and memory functioning among Chinese patients with multiple sclerosis (MS) were investigated in order to identify cross-cultural differences in the impact of MS on cognitive functions. RESEARCH DESIGN, METHODS AND PROCEDURES: Cognitive profiles of 11 Chinese patients with MS were compared to that of their corresponding matched h...

Memory deficits in epileptic patients have been found in some, but not all studies assessing the effects of side of seizures and resection from a temporal lobe on cognitive performance. The purpose of this study was to provide a quantitative review of previous studies on this issue. Based on conventional meta-analytic procedures, we identified 33 s...
